Fast Start Gives Way to a Tough Back Stretch Ryan Van Duzer completed the 2026 Boulderthon Marathon in 4:21:49, well off his 3:24:27 finish in 2025 and his 3:27:19 result in 2023. The race opened briskly, with Van Duzer clicking off his first four miles in roughly 7:08 elapsed pace and staying under 7:36 elapsed pace through mile 12. That effort held remarkably steady into the mid-miles, with elapsed pace still under 8:00 per mile through mile 17. The second half told a different story: splits climbed into the 1216 minute range from mile 20 through 24, coinciding with the stretch that includes the lululemon Power-Up Zone near mile 22.5, before he closed with an 8:07 final mile. The opening 12 miles stand out as his strongest sustained running of the day, a clear contrast to the fade that followed.
